Dilaudid, or hydromorphone, is a strong opioid analgesic frequently prescribed for managing moderate to severe pain, especially in patients who may not respond adequately to other pain relievers. By binding to mu-opioid receptors in the brain and spinal cord, Dilaudid modifies how the body perceives pain and can also affect emotional responses to discomfort. It comes in various formulations, including immediate-release tablets, extended-release tablets, liquid solutions, and injectable forms, allowing for tailored pain management strategies.
